  x-api-evangelist-provenance: 'Derived by the API Evangelist enrichment pipeline from the live WordPress REST route index at https://belharratx.com/wp-json/ (198 routes across 11 namespaces) and verified against live anonymous responses on 2026-08-06. Every parameter below appears verbatim in the route index `args` for that endpoint, every schema property was read from a live anonymous response body, and every collection count in a description was read from the `X-WP-Total` response header on that date. Belharra Therapeutics publishes no OpenAPI, no developer documentation and no API reference for this surface; the humanURL in apis.yml points at the upstream WordPress REST handbook that defines the wp/v2 contract. The deployment is served by WP Engine behind Cloudflare, and API responses carry `x-robots-tag: noindex` and `cache-control: max-age=600, must-revalidate`. Nothing here was obtained with credentials.'
